python object cannot be re-sized

This statement is not entirely true. In Python, some objects are immutable, which means they cannot be resized or modified once they are created. Examples of immutable objects include integers, floats, tuples, and strings. On the other hand, some objects are mutable, which means they can be resized or modified after they are created. Examples of mutable objects include lists, dictionaries, and sets.

However, it is important to note that even mutable objects have some limitations on their resizing capabilities. For example, if a list is resized frequently, it can lead to performance issues due to the need for frequent memory reallocations. Therefore, it is important to consider the trade-offs between mutable and immutable objects when designing a program.
